New study suggests how rod photoreceptors may have originated to give rise to nocturnal mammals

Retinas from our earliest vertebrate ancestors had cone-like photoreceptors, presumably allowing them to see in daylight, but little ability to see at night. Then, millions of years ago in the Mesozoic era, and in relatively short order, mammals emerged that had retinas with predominantly rod photoreceptors, allowing for them to see at night perhaps to hunt for food while their dinosaur predators were dozing.

Delayed healing linked to weaker electrical currents in diabetic wounds

People with diabetes often suffer from wounds that are slow to heal and can lead to ulcers, gangrene and amputation. New research from an international group led by Min Zhao, professor of ophthalmology and of dermatology at the University of California, Davis, shows that, in animal models of diabetes, slow healing is associated with weaker electrical currents in wounds.

Mice study highlights vital role of liver in balancing fats and sugars

Sugar in the form of blood glucose provides essential energy for cells. When its usual dietary source — carbohydrates — is scarce, the liver can produce it with the aid of fat.

Study shows for-profit hospices have persistently high rates of hospitalization

Patients who were asked where they wanted to die upon entering hospice had lower rates of hospitalization at the end of life, as did those in hospices that monitored symptoms more frequently, according to a new study led by researchers at the Icahn School of Medicine at Mount Sinai.

New, portable molecular imaging system combines optical imaging and scintigraphy

Bigger isn't always better, especially when it comes to a new and surprisingly portable molecular imaging system that combines optical imaging at the surface level and scintigraphy, which captures the physiological function of what lies beneath, announced developers at the 2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging.

Autonomic nervous system plays role in promoting memory consolidation during sleep

A team of sleep researchers at the University of California, Riverside, led by psychology professor Sara C. Mednick, has found that the autonomic nervous system, which is responsible for control of bodily functions not consciously directed (such as breathing, heartbeat, and digestive processes) plays a role in promoting memory consolidation - the process of converting information from short-term to long-term memory - during sleep.
